Alimak konfigurerar industrihissen Alimak SE 1200 med en Ex-klassificering f\u00f6r att uppfylla kraven f\u00f6r explosionsfarliga omr\u00e5den p\u00e5 North Rankin A-gasplattformen. Med externa anropsstationer kan bagagehissen anropas, lastas och dirigeras till \u00f6nskad niv\u00e5, utan personal i hisskorgen.<\/p>\n\n\n\n

Plattformens utvidgning<\/h4>\n\n\n\n

Ombyggnaden och utvidgningen av North Rankin A-plattformen av Woodside-baserade North West Shelf Project inkluderar installationen av en ny North Rankin B-plattform, f\u00f6rbunden till den befintliga North Rankin A-plattformen med tv\u00e5 100 m l\u00e5nga broar. NRA-plattformen ligger 135 km nordv\u00e4st om Karratha och \u00e4r en av de st\u00f6rsta plattformarna i v\u00e4rden f\u00f6r gasproduktion med en daglig produktion p\u00e5 mer \u00e4n 51 000 ton gas och gaskondensat.<\/p>\n\n\n\n

Kuggst\u00e5ngsdriven bagagehiss<\/h4>\n\n\n\n

I mars 2012 installerade Woodside en Ex-klassad Alimak SE 1200-industrihiss p\u00e5 North Rankin A-plattformen. Bagagehissen \u00e4r tillg\u00e4nglig 24 timmar om dygnet f\u00f6r boende ombord p\u00e5 plattformen och transporterar personalens bagage fr\u00e5n toppen av boendemodulen till landstigningsplatsen f\u00f6r fotg\u00e4ngare p\u00e5 den s\u00f6dra bryggan.<\/p>\n\n\n\n

<\/p>\n\n\n\n

Alimaks utmaning<\/h4>\n\n\n\n

Kraven f\u00f6r farliga omr\u00e5den p\u00e5 gasplattformen gav Alimak tre utmaningar i projektet: f\u00f6r det f\u00f6rsta att hissen skulle konfigureras med Ex-klassning; f\u00f6r det andra att hissen skulle kunna k\u00f6ras med externa reglage utan personal i hissen; och f\u00f6r det tredje att installationen skulle utf\u00f6ras b\u00e5de p\u00e5 land och till havs f\u00f6r att minska tiden som kr\u00e4vdes f\u00f6r att slutf\u00f6ra installationen, testningen och drifts\u00e4ttningen p\u00e5 sj\u00e4lva plattformen.<\/p>\n\n\n\n

<\/p>\n\n\n\n

En Ex-klassad hiss<\/h4>\n\n\n\n

Med tanke p\u00e5 hissens placering p\u00e5 en offshoreplattform f\u00f6r gasproduktion dikterade kraven f\u00f6r farliga omr\u00e5den att hissen skulle konfigureras med en Ex-klassning. Alimak arbetade i n\u00e4ra samarbete med kunden f\u00f6r att s\u00e4kerst\u00e4lla att hissen uppfyllde b\u00e5de kundspecifikationerna och omr\u00e5deskraven. F\u00f6r att uppn\u00e5 en Ex-klassning konstruerades och tillverkades hissen i enlighet med de angivna kraven f\u00f6r farligt omr\u00e5de, klassificerad under zon 2, gasgrupp IIA och temperaturklass T3. I enlighet med hissens Ex-klassning tillhandah\u00f6ll Alimak ett komplett paket med fullst\u00e4ndig Ex-dokumentation och drifttagning f\u00f6r installationsfaserna p\u00e5 land och till havs.<\/p>\n\n\n\n

<\/p>\n\n\n\n

Externa reglage<\/h4>\n\n\n\n

Eftersom det kr\u00e4vdes att hissen skulle tillhandah\u00e5lla ett s\u00e4kert s\u00e4tt att transportera bagage ombord plattformen under alla v\u00e4derf\u00f6rh\u00e5llanden, var det n\u00f6dv\u00e4ndigt att utrusta hissen med externa anropsstationer f\u00f6r drift utan personal i hisskorgen. I enlighet med kundens specifikation \u00e4ndrade Alimak den elektriska styrkretsen och inkluderade en funktion f\u00f6r att ”kalla och skicka” hissen. Med tanke p\u00e5 att bagagehissen endast var f\u00f6r transport av material kunde personalen med dessa reglage k\u00f6ra hissen utan att sj\u00e4lva beh\u00f6va \u00e5ka med i hisskorgen. P\u00e5 detta s\u00e4tt kunde operat\u00f6rerna ”kalla” p\u00e5 hissen med de externa anropsreglagen som sitter p\u00e5 taket p\u00e5 boendeutrymmet och landstigningsplatsen f\u00f6r fotg\u00e4ngare p\u00e5 den s\u00f6dra bryggan och sedan ”skicka” hissen till \u00f6nskat plan.<\/p>\n\n\n\n

Alimak slutf\u00f6rde installationen p\u00e5 land och till havs, testning och drifttagning av hissen f\u00f6r att minimera installations- och utbildningstiden ombord p\u00e5 plattformen.<\/p>\n\n\n\n

<\/p>\n\n\n\n

Installation p\u00e5 land och till havs<\/h4>\n\n\n\n

F\u00f6r att minimera installations- och utbildningstiden ombord p\u00e5 plattformen slutf\u00f6rde Alimak drifttagningen p\u00e5 land och till havs, samt genomf\u00f6rde utbildning i underh\u00e5ll och drift av hissen. Landinstallation \u00e4gde rum p\u00e5 AOG-varvet i Kwinana, v\u00e4stra Australien. Hissen konstruerades och uppf\u00f6rdes vid landanl\u00e4ggningen, vilket gjorde att den kunde genomg\u00e5 fullst\u00e4ndig installation, testning och drifttagning inuti det konstruerade hisschaktet. Efter landinstallationen stagades hisskorgen inuti hisschaktet, v\u00e4ndes p\u00e5 sidan och transporterades till offshoreplattformen f\u00f6r den sista drifttagningsfasen.<\/p>\n\n\n\n

Efter installationen p\u00e5 offshoreplattformen genomgick hissen och hisschaktet det sista steget av testning och drifttagning, och samtidigt genomf\u00f6rdes personalutbildning utf\u00f6rd av Alimak-certifierade tekniker.<\/p>\n\n\n\n

Alimak SE-Ex 1200-hissen har varit i drift p\u00e5 North Rankin A-plattformen sedan mars 2012. Bagagehissen \u00e4r konstruerad f\u00f6r intermittent service och har en f\u00f6rv\u00e4ntad livsl\u00e4ngd p\u00e5 minst 30 \u00e5r med regelbundet underh\u00e5ll.<\/p>\n\n\n\n
